You can't use every day experiences to determine what will happen at speeds approaching light. When an electron approaches the speed of light, it's tiny insignificant mass will be multiplied by the Lorenz Factor (referred to as gamma):
gamma = 1/(sqrt(1-v^2/c^2))
where c is the speed of light, and v is velocity.
i.e., if v = 99.999999% of the speed of light, then the electron's mass would be about 7000 times it's normal mass.
if v = the speed of light, then it's mass goes up to infinity. That's a no no.
